SPECIFICATION forming part of Letters Patent No. 270,426, dated January 9, 1883.

7 Application filedAugust 2'2, 1882. (No model.)

To all whom it may concern Be it known that I, ISAIAH HANCOCK, of Fayetteville, in the county of Lincoln and State of Tennessee, have invented a new and Im- 5 proved Cultivator-Plow, of which the follow ing is a full, clear, and exact description.

' My in vention relates to improvements in the class of plows having more than one plowshare, and having swinging beams, by which the plows may be adjusted closerto or fart-her from each other, as may be desired.

In my improved plow the beams of the plow are united by means of curved pivot-bars and straight holding and adjusting bars, so

that the beams shall be rigidly held at any desired distance apart. The plow-handlesare united to the plow-standards and to the beams to make them firm, and their upper ends are adjustable on the round thatunites them. The

plowshares are provided with auxiliary wings that may be attached or detached without removing the shares from their standards' Reference is who had to the accompanying drawings, forming part of this specification,

2 in which similar letters of reference indicate corresponding parts in both the figures.

Figure l is a perspective view of my improved plow. Fig. 2 is a side elevation of the same.

In the accompanying drawings, A is the main or draw beam of the plow, and B is a swinging auxiliary beam, secured to the main beam A by means of two curved bars, a. b, rigidly bolted to the top and bottom of the frontend of the beam B, and which are pivoted to the beam A by means of a bolt pass ing through holes in the outer ends of the bars and vertically through the draw-beam A at a distance of about one-third of its length from 40 the front end. The auxilary beam B is about one-half the length of the main beam A, and is adjustably secured at its rear end to the beam A by two straight holding-bars, c d,pivoted by a bolt to the beam A, and correspondingly perforated ncartheir outer ends to receive a screw-bolt tbatpasses through the bars 0 d, and through the beam B near its rear end. By this means the beam B is adapted to be adjusted at a greater or less distance from the beam A by placing the bolt in different holes in the bars 0 d. The beams A and B are flat on their upper and lower surfaces, and when the bolts of the adjusting-bars are screwed up firmly the beams are held rigidly in relation to each other. i

' At the rear end of the beam A is secured a plow-standard, O, at such an inclination that the plow E, attached to its lower end, enters the ground at a proper angle, and the upper end is elongated to intersect with and sustain the handle G of the plow. On the. auxi iary beam B a plow-standard, D, is secured, in front of the bars 0 (I, having the same inclination as the standard 0, and aplow, F, secured toit at its lower end. lts upper end intersects and 6 sustains the plow-handle H. The plow-handle G is attached at its lower end to the beam A, and at its upper end to the top of the plowstandard (J, and the handle H is attached at its lower end to the beam B and at its upper. to the top of the standard D. A little in front of their upper ends the handles G and H are connected to each other by an adjusting-round. I, that is rigidly secured to the handle H, and extends through the upper end of the standard C and the handle G.. This end of the round is perforated to correspond with the holes in the bars 0 d, and a pin or screw, 0, which passes vertically througll the handle H, also passes through the perforations of the round I and secures the handles G and H at any desired distance apart. With this construction of the beams, standards, and handles the plows are easily adjusted, and when adjusted are very firm and rigid.

The plows E F are of the ordinary construction and secured to the standards D E in the usual manner. To one side of the plow-standards, a little below the upper ends of the plows, are placed wings or auxiliary mold-boards J J, 0' that are provided at their sides next to the plow-standards with ears, ff, (shown in Fig. 2,)thatare perforated to receive bolts by which the wings are secured to the standards. It will be seen that with this construction the wings 5 can be readilyattached and detached without removing the plows E F from their standards. The object of the wings is to turn over the edges of the furrows after they have been raised by the plows E F. :00
